In the course of our work at the District Attorney’s Office, we often discover new and better ways to look at, organize, and interpret the data. We make changes and updates to the Public Data Dashboard to keep it as accurate and informative as possible. We also want to be clear to users of this site about the changes we’ve made. This page is a timeline of updates, fixes, and changes that we’ve implemented.
We have added a DAO Publications section to the Research Page. This section includes reports on internal studies at the District Attorney’s Office.We have also reorganized the menu to simplify it and make it more clear which reports are year-to-date and which are year-end.
We have added a line denoting March 2020 to all reports. This was the month that the COVID-19 pandemic forced a shutdown of many essential government functions in Philadelphia, including the court system. It also lead to several policy changes in the Philadelphia Police Department and at the District Attorney’s Office. The purpose of this addition is to enable users of the site to more easily view the data in the context of the pandemic.We have also changed the text of two firearms labels to more clearly state what the data shows: ‘All Firearms Offenses’ has become ‘All Firearms Possession’ and ‘Possession of Firearms’ has become ‘Illegal Firearms Possession’.
Updates and fixes, including:
You can now download daily data by ZIP Code Tabulation Area and weekly data by Census Tract. This was one of the most popularly requested features. Please see the Limitations page for more information on these datasets.
We have added 8 new offense categories to the misdemeanor/felony reports: Other Assaults, Sexual Assault and Other Sex Offenses, Fraud/Theft of Services, Embezzlement, Possession of Firearms, Prostitution/Sex Work, Patronizing Prostitutes, and Threats of Violence. Similar categories were added to the Incidents report, although the incidents data available on OpenDataPhilly is not as fine-grained as our other data so the new incident categories are a bit more general.
We have added two new tabs: Firearms and Other.
We have now added reports on summary offenses for Arrests, Charges, Case Length, and Case Outcomes. These help to fill a hole in the original dashboard, which only reported on felony and misdemeanor offenses and therefore missed an important part of the system. Many of the offense categories reported on are the same as for felony and misdemeanors, although several are not reported on (e.g. violent offenses tend to not be summaries) and others have been added (e.g. Disorderly Conduct). In all, we report on the 9 most common summary offenses.
You can now view year end data as well as year to date data. Year end reports are available through the navigation menu at the top of the page. Rather than just viewing what has happened since January 1 of each year, these reports allow you to view years as a whole.
A small error was found in how we have been connecting arrests to case information. This caused a small number, about 0.5%, of cases to be duplicated in the Charges, Bail, Outcomes, Case Length, Future Years of Incarceration, and Future Years of Supervision reports. This error has been fixed, and the total count of cases in these reports have decreased slightly as a result.
The line chart on the Violent Offenses tab on the Bail Report was reporting by quarter. This has been changed to report by month.
The Arrests report inadvertantly excluded arrests where there was no date of birth listed for the defendant. These cases are now included.
A bug causing some Safari users to experience issues when interacting with the report tables has been fixed.
Various bug fixes, including:
Fixed header scaling on small screens.
A broken link to our GitHub Repository on the How to Use This Site page has been repaired.
Fixed how some ‘Key Metrics’ arrow symbols render on iOS devices.
Changed how many significant figures are shown on the Rates tab on the Future Years of Supervision and Future Years of Incarceration reports.
